DISH-WASMR.

Specication of Letters Patent.

Application. filed. June 24, 1908. Serial No. 440,079.

To all'whom it may concern:

Be 1t known that l, CHARLES CARs'rENs, citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Dish-Washers, of which the following is a specification.

This invention is a dish-washing apparatus characterized particularly by improvement with respect to a sprinkling device and a rack arrangement for holding the dishes to be washed. The construction is such that the dishes can be readily placed in or removed from the washer, and the apparatus is sanitary, having no inaccessible corners'or places for the accumulation of dirt.

The apparatus is illustrated in the accompanying drawings, in which- Figure l is a front elevation, with the doors of the casing or cabinet removed. Fig. 2 is a vertical section on line 2-2 of Fig. 1, with' the doors in place.l Fig. 3 is a detail of a traveling nut for operating the sprinkler.

a Referring specifically to the drawings, a lndicates an upright cabinet or casing -ned with galvanized sheet metal and rovidedat the front With doors a which ave extended hinges as at a2, at the sides of the cabinet, to open out of the operators way. Within the upper part of the casing are racks b, formed| of spiral springs, for holding plates and such :flat dishes in upright and separate position. These springs are fastened to the ends of the cabinet by means of clamps e, and are supported by cross rods f thereunder.

Racks g made from galvanized wire screens bent zigzag, as shown for receiving cups, tumblers, combs etc., are fastened similarly at the ends of the cabinet and located in somewhat inclined position inwardly.

Hot Water is forced upon the dishes, b the traveling pipe s Irinkler h with branc arms h1 located close y under and beside the racks. The pipes are tted with nozzles L which allow of better adjustment and direction of the water spray and protect the `openings from excessive wear, and the nozzles can be flattened with a hammer or pliers to suit the water pressure. v

The sprinkler is carried by a traveling nut j, being fastened thereto with clamps c. Nut

7 1s a split cylinder with a loose follower nut e fitting a bore for the same. The nut has a projection@1 engaging the thread of screw m, which revolves in bearings n, on top of the cabinet. The screw m has both right and left hand threads of steep pitch which meet and unite at the ends in loops o, giving the sprinkler h a reciprocatingmotion traveling back and forth over the dishes a suflicient number of times to clean the dishes. The screw fm is driven by pulley or flexible shaft from a small motor.

ln front of the cabinet is a'tank q, for cold Water, and for holding dishes ready for cleaning. Overflow from this tank goes into cabinet through hole r and drains at bottom of machine into a large bowl s with removable strainer t for accumulating grease and preventing same from clogging up the drain and v 'sewer pipe.

ln use, the dishes are placed in or upon the racks as described and the doors of the cabinet are closed. The screw is started and hot water turned on, causing the sprinkler tov travel back and forth across the cabinet and spray and Wash the dishes.

Various modifications may be made in the construction of the apparatus, Within the scope of the invention, particularly with respect to the location of the racks .and the sprinkling pipes. A

It is to be particularly noticed that there is great economy of water, as the sprinkler acts on only a few dishes ata time, as it travels back and forth, instead of on all the dishes in the cabinet. Hence the pressure of an ordinary cit water main will be suficient to discharge t e Water with the necessary force to d1slodge the dirt from the dishes, whereas if the sprinkler discharges over the whole cabinet'at once, additional pressure would have to be supplied from some source of power. This is an important feature under conditions where Water under high pressure can not be obtained.

I claim: l l

1. A dish-washer comprising a cabinet having dish racks therein, and a sprinkling pi e .movable back and forth across the ca inet and having branches projecting between the racks and jet openings directed toward said racks. s

2. A dish-Washer comprising a cabinet having openable doors atthe front and a slot at the top having dish racks therein, a pipe depending through the slot and within the cabinet beside the racks and having branches extending adjacent to said racks and pro- Y pipe arranged to spray dishes on the racks and fastened to and carried by the nut.

vided With nozzles directed toward the same, and means to support the pipe end to reciprooete the same laterally in the slot and cabinet.

3. A dish-Washer comprising a, cabinet having 'dish reeks therein, an endless re Versing screw extending across the cabinet, a traveling mit on the screw, and a spraying
